The production of ionizing photons in UV-faint z ∼ 3–7 galaxies

Aims. The demographics of the production and escape of ionizing photons from UV-faint early galaxies is a key unknown that has hindered attempts to discover the primary drivers of reionization. With the advent of JWST, it is finally possible to observe the rest-frame optical nebular emission from in...

Zusammenfassung:	Aims. The demographics of the production and escape of ionizing photons from UV-faint early galaxies is a key unknown that has hindered attempts to discover the primary drivers of reionization. With the advent of JWST, it is finally possible to observe the rest-frame optical nebular emission from individual sub- L * z > 3 galaxies to measure the production rate of ionizing photons, ξ ion . Methods. Here we study a sample of 370 z ∼ 3 − 7 galaxies spanning −23
